I read a post that indicated that UMA capability is coded into the firmware of the Bold. I am on ATT and have an unlocked Rogers Bold. I cannot call via UMA and was hoping that I might get this functionality when I upgrade to the ATT OS. Am I out of luck??

Second, if I select the hotspot browser in browser options, it automatically reverts to blackberry browser when I save it. When I look at services status it indicates that Blackberry internet service and Blackberry enterprise server are connected to WiFi. Am I browsing over WiFi??

That makes me wonder if you can do UMA with an ulocked TMob Curve that is unlocked... time to search for my answer..

The answer is no. You won't be able to do this because AT&T doesn't have the necessary setup to do UMA. Its not just the firmware/hardware support you need. It also needs to be supported and setup on the carrier side as well.

The article then lists 4 possible Wi-Fi phones including the 9000, 8120, 8320, and 8820 models. (Perhaps there needs to be a 9020 to make this list complete). Of course the new KickStart/Pearl is also UMA compatible. I believe that model is 8220. The units run the identical operating system to the Bold...
